Guide ranges for supply & fit; controls and commissioning by a smoke-control specialist. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building warrant fees, where a job needs them, are shown as their own line.
Fitting across Dumbarton and nearby
Covering Dumbarton means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in G82, G83 and G60, and are happy to quote further out in Vale of Leven and Erskine. If your address sits between towns, tell us and we will confirm whether it falls in our normal area or needs travel set out separately on the quote.
What we do on the day
- Upstand checked, adapted or rebuilt to the vent maker's drawing
- Commissioning and sign-off carried out by the specialist before handover
- Certified vent and actuator matched to the opening and controls
- Fire rules near escape routes — We check the roof around the vent for fire rules that affect it.
- Free area at the stair head — We check the free area the vent must provide before choosing a replacement.
A typical installation day
Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a smoke vent rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes one to two days per vent.
Do you need permission in Dumbarton?
In Scotland, smoke ventilation is covered by the domestic or non-domestic Technical Handbook, depending on the building. Vents must be certified products, keep the required free area, and be connected and commissioned by a smoke-control specialist. A building warrant is needed where the system is altered.
Details that speed up your quote
What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around G82 and we will come back with a quote or a survey date.
Common questions in Dumbarton
How does payment work?
Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.
How long does fitting take?
Fitting a smoke vent rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.
Does a rooflight need a building warrant?
In Scotland a new rooflight needs a building warrant from the council before work starts. Replacing a rooflight complete with its frame doesn't need a warrant, but the new unit must meet the building standards in full, including 1.6 W/m²K. We confirm which applies to your job before you commit.
